We're dividing 390303 by 57 
Our goal is to divide 390303 by 57.

Going ahead to step 1:
57 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 57

Advancing to step 2:
39 divided by 57 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 57

Let's proceed to step 3:
The number 57 fits into 390 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 48 after subtracting 342 from 390.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 57

Step 4:
57 can be fit into 483 8 times, resulting in a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 456 from 483 leaves us with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 57

Step 5:
57 can be fit into 270 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 684.0
If we take 228 away from 270, we end up with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 57

Step 6:
The number 57 fits into 423 7 times, leaving a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 6847.0
Subtract 399 from 423 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
57 can be fit into 240 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 6847.4
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
When dividing 120 by 57, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 6847.42
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 57, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 6847.421
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
57 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 6847.421
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 57, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6847.42105
The remainder is 15 after subtracting 285 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
150 divided by 57 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 6847.421052
If we take 114 away from 150, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
57 can be fit into 360 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 6847.4210526
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
57 goes into 180 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 6847.42105263
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 6847.42105263 with a balance of 9e-09.
